For a cone, the equation for volume would be
V = π r^2 h/3.
( volume = pi x radius squared x height / 3)
To find the volume for this question, you would set up the equation like this:
V = π x 2^2 x 12 / 3
Then, following the order of operation, you would do the following:
V = π x 4 x 12 / 3
(You get the 4 from 2 squared)
V = π x 4 x 4
(You get the second 4 from dividing 12 by 3)
V = π x 16
(You get 16 from multiplying 4 and 4)
V = 16π
(You get 16π from multiplying 16 and π, and the number is always in front of the π, so you would never get a π16, it would only be 16π)
So, your volume would be 16π, which is answer D.

Answer:
y = 3x -2
Step-by-step explanation:
If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.
You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.
y = m*x + b
7 = 3*3 + b
7 = 9 + b
-2 = b
y = 3x -2

2x + 8 = 44
2x = 36
x = 18

X= 10 m1= 52 degrees m2= 38 degrees. You find x by solving the equation (5x+2)+(3x+8)=90.
